U.S. President Donald Trump announced on Thursday that his administration will «permanently pause migration from all Third World Countries», following the killing of a National Guard member in an attack near the White House. Investigators say the attacker was an Afghan national who entered the U.S. in 2021 through a resettlement program created after the fall of Kabul. Trump said the freeze would also apply to cases approved under the Biden administration, vowing to «terminate all of the millions of Biden illegal admissions» and remove anyone he deems «not a net asset to the United States». He also pledged to cut federal benefits for non-citizens, «denaturalize migrants who undermine domestic tranquility», and deport any foreign national considered a security risk or «non-compatible with Western civilization». The United Nations called on Washington to respect its international obligations. «We expect all countries, including the United States, to honour their commitments under the 1953 Refugee Convention», UN spokesperson Farhan Haq told Reuters, commenting on Trump's decision. The UN human rights office added that asylum seekers must receive due process. According to Homeland Security officials, Trump has already ordered a broad review of asylum cases approved under Joe Biden and of Green Cards issued to citizens of 19 countries. U.S. immigration services have also suspended all Afghan-related applications.
